HPLC autosampler vials  are generally categorized by vial diameter, vial height, and thread finish. Clear glass and amber glass have similar inert properties. Amber glass is used to protect sensitive samples from UV light. 

Aijiren screw thread top sample vials design is characterized by universal ease of use, especially the use of automated sample introduction systems, so this type of vial is also called a autosampler vial. And this sample vial is extremely compatible. The 1.5ml sample vial we usually say is the 2ml volume sample vial. The design of Aijiren screw thread top vials are developed from Europe and the United States, and the design feature is easy to use, especially the use of automated sample introduction system. Aijiren screw thread top vials also known as autosampler bottles.

PVDF syringe filters have excellent chemical compatibility, mechanical strength and low extractability. In these filters, the maximum allowable housing pressure is 150 psi. It improves the filtering speed. These filters have high temperature resistance due to their materials. They have excellent flow rate and temperature stability.

PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing.

Caps with solid PE liners offer good chemical resistance and low moisture vapor transmission rate and is great for nail polish remover and higher concentration acids & alkalis. Good for non-oil products filled at room temperature. Because this lining system is paperless, your samples will not be contaminated with fiber or paper particles from the closure. Available in Phenolic caps.

Aijiren Storage vial is an ideal device for general laboratory use and storage of diverse samples due to excellent sealability and chemical tolerance.
Besides, chemically inert caps are a good choice for most chromatography and storage applications. Top grade PTFE or Silicone septa are adopted to ensure cleaning production and consistent quality of sample vials.

50 holes polypropylene autoclavable vial rack is a specialized laboratory accessory used for holding and organizing vials during autoclaving, storage, or transport. It is commonly made of polypropylene, a durable and heat-resistant plastic material that can withstand autoclaving temperatures.
It’s important to note that the specific design and capacity of polypropylene autoclavable vial racks may vary depending on the manufacturer and intended use. It’s recommended to choose a vial rack that is compatible with the vial sizes and quantities you frequently work with in your laboratory.

The manufacturer’s lot number for each component of this product is tracked until all procedures are completed at which time a final lot number is assigned and documented. A randomly selected collection of vials from each completed lot are submitted to an independent validation laboratory for quality control purposes to confirm that the TOC vials comply with the quality specification. The vial, closure and dust cover undergo comply with stringent quality standards and specifications.

4ml 13-425 hplc vial with screw cap is belong to HPLC autosampler vials. The classification of HPLC autosampler vials is generally done based on the diameter of the vial body, vial height, and thread finish. Clear glass and amber glass present similar inertness. 4ml 13-425 hplc vial with screw cap is compatible to SHIMADZU instrument. Autosampler needle pierces through the cap during injection and withdraws the required amounts of analyte from the sample vial.

1. The glass adopts high-quality borosilicate glass tube, with low free ion content, low expansion coefficient and very high chemical resistance.
2. The unique thread design can ensure the consistency of the seal.
3. Strict quality assurance provides dimensional consistency between batches.
4. It is suitable for autosampler of Aijiren, Shimadzu, Waters, CTC/Leap and other companies.

Vial micro insert is used to ensure the most accurate and reliable analysis of your lab samples. Micro Inserts allow for maximum sample recovery and easier sample removal when combined with hplc autosampler vials.

Aijiren’s PVDF syringe filter has hydrophilicity and good chemical compatibility. They can bring precision to your research and ensure the highest level of performance. Our filter series are designed with female Leur-lock inlet and male Leur-slip outlet. In addition, these filters have better mechanical resistance and can withstand high temperatures.

Micro volume vial inserts, when used in conjunction wit […]

Micro-insert, also known as a micro-insert vial or microvial insert, is a small glass or plastic container that is used in chromatography and analytical techniques to enable smaller sample volumes to be analyzed in standard-sized vials.
Micro-inserts are designed to fit inside standard-sized sample vials, which are typically larger in size. They are used when the available sample volume is limited or when the sample concentration is low. By using a micro-insert, the sample volume can be reduced, allowing for more efficient analysis and minimizing the risk of sample loss or evaporation.

Aijiren’s products enable pharmaceutical companies to increase productivity. Syringe filters and vials reduce HPLC sample preparation time and consumables usage, and track-etched and membranes are also vital to extruding liposomes for encasing and targeting drugs.

Aijiren 10mm wide opening screw vial 2mL, 12x32mm 10mm wide opening screw vial and insert. 10-425 thread finish. The vial has a calibrated write patch that is useful for identifying samples. The neck opening is wide and easy to fill.

Polypropylene Snap Micro Vials can be used in most standard gas and liquid chromatography autosamplers. The conical interior ensures maximum retrieval of contents without the hassle of using removable liners.

Headspace vials are a type of laboratory vials used for gas chromatography. They are designed to contain samples that will be analyzed using headspace gas chromatography, a technique used to analyze volatile compounds in solid or liquid samples. The vials are sealed with a septum cap, allowing the headspace above the sample to be analyzed without exposing the sample to the atmosphere. This technique is commonly used in pharmaceutical, environmental, and food analysis, among other fields.
Headspace vials, also known as gas chromatography (GC) vials or sample vials, are specialized containers used for the analysis of volatile compounds in gas chromatography. They are designed to store samples and create a headspace above the sample, which contains the volatile components to be analyzed.

100ml lab glassware reagent bottle refers to a specific type of laboratory glass container designed to hold and store reagents, chemicals, or other liquids used in scientific experiments or analysis. It has a capacity of 100 milliliters, which means it can hold up to 100 milliliters of liquid.
These bottles are typically made of high-quality borosilicate glass, which is resistant to heat and chemical reactions. They often have a narrow neck and a screw cap or stopper to ensure a tight seal and prevent any leakage or contamination.
Lab glassware reagent bottles come in various sizes, ranging from small volumes like 5ml or 10ml up to larger sizes like 500ml or 1000ml. The 100ml size is commonly used when smaller quantities of reagents are needed for experiments or when space is limited.

11mm vials for GC and HPLC. Vials have a 40% larger opening than standard opening aluminum seal vials. Crimp vials are manufactured of Clear or Amber borosilicate glass.

Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The crimp cap vial requires crimping tools to carry out the sealing process.

Aijiren Crimp Top vials are excellently fitted for autosamplers and have good chemical compatibility and super cleanliness. The crimp top sample vial is the most commonly used gas sampling vial on the market at present. 2ml volume sample vial especially suitable for laboratory use.
